The intervention continuum in restoration ecology: rethinking the active–passive dichotomy
Open accessAbstract
The distinction often made between active and passive restoration approaches is a false dichotomy that persists in much research, policy, and financial structures today. We explore the contradictions imposed by this terminology and the merits of replacing this dichotomy with a continuum‐based intervention framework. In practice, the main distinction between “passive” and “active” restoration lies primarily in the timing and extent of human interventions. We apply the intervention continuum framework to forest, grassland, stream, and peatland ecosystems, emphasizing that a range of restoration approaches within the scope of ecological or ecosystem restoration are typically employed in most projects, and all can contribute to the recovery of native ecosystems and prevention of further degradation. As restoration is fundamentally about the recovery of ecosystems, eliminating human sources of degradation is essential to enable ecosystem recovery processes, regardless of subsequent interventions that may be needed to assist recovery. Our review of restoration practices involving different levels of intervention highlights the benefits of recognizing a broader suite of restoration interventions in the financial and policy frameworks that currently underpin restoration activity. Effective restoration interventions emerge from an understanding of nature's intrinsic recovery potential and overcoming specific obstacles that limit this potential.

The synthesis refutes the implicit assumption of ecosystem service-oriented forest restoration initiatives that tree plantations can deliver ecosystem services as effectively as native forests.
“Our synthesis refutes the implicit assumptions of ecosystem service-oriented forest restoration initiatives such as China's Grain-for-Green Program covering >34 million hectares (37,38), and a large collection of projects targeting carbon storage (39), soil conservation (40), and water provisioning (41) that have focused mostly on establishing (monoculture) tree plantations.”
From The biodiversity and ecosystem service contributions and trade-offs of forest restoration approaches (2022) · cites this paper as [37]
The Forest ecosystems section discusses natural regeneration, tree planting, and ecosystem services such as soil fertility and water quality, but it does not compare the services delivered by plantations and native forests. Searches for monoculture plantations, water provisioning, and Grain-for-Green found no passage addressing the claimed assumption or its refutation; the available passages have no page numbers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
